摘要
Thanks to the large binding energy and excellent optical properties of Frenkel excitons,organic semiconductors emerge as ideal platforms for the realization of room-temperature exciton polariton(EP)Bose-Einstein condensates(BEC),which is of great importance for developing on-chip coherent light sources and optical logic elements.Previous demonstrations usually demand complex fabrications with external microcavities,which largely hinders the practical applications in on-chip integration.Recently.
